The Nature Of Science: A Perspective From The Philosophy Of Science, Juli T. Eflin, Stuart Glennan, George Reisch

Scholarship and Professional Work - LAS

In a recent article in this journal, Brian Alters (1997) argued that, given the many ways in which the nature of science (NOS) is described and poor student responses to NOS instruments such as Nature of Scientific Knowledge Scale (NSKS), Nature of Science Scale (NOSS), Test on Understanding Science (TOUS), and others, it is time for science educators to reconsider the standard lists of tenets for the NOS. Alters suggested that philosophers of science are authorities on the NOS and that consequently, it would be wise to investigate their views of current NOS tenets. To that end, he conducted a …

Book Review: Swallow Summer, Peter E. Lowther

Journal of the Iowa Academy of Science: JIAS

Swallow Summer. Charles R. Brown. 1998. The University of Nebraska Press, Lincoln, NE. 371 pages. ISBN 0-8032-6145-4.

This book, Swallow Summer, is a popular account of the Browns fifteenth year at Cedar Point Biological Station in Keith County, Nebraska. Brown presents a daily log of the activities that he undertakes for the 1995 field season, describing the work supporting his research program. In the preface, Brown hopes Swallow Summer can explain his fascination with Cliff Swallows and why he enjoys his research. His intent is to describe "the challenges, thrills, and frustrations that come with studying wild animals in the …

Morphology, Ultrastructure, And Function Of Extrafloral Nectaries In Three Species Of Caesalpiniaceae, Lenore T. Durkee, Matthew H. Haber, Lisa Dorn, Ann Remington

Journal of the Iowa Academy of Science: JIAS

Light and electron microscopy reveal that the morphologically well-differentiated petiolar nectaries of Chamaecrista fasciculata, Senna hepecarpa, and S. marilandica have an unusually simple anatomy consisting of an epidermis immediately subtended by a mass of small, loosely-packed parenchyma cells. Vascular strands from the petiolar bundles enter the nectary and terminate as phloem within or near this parenchyma. In mature, secreting nectaries, the cuticle of the epidermis extends between the epidermal cells and into the nectary parenchyma, where it occupies, but does not occlude, much of the free space of this tissue. The cutin is not found below the level …

Comparing Three Bee Species For Controlled Pollination Of Selected Brassicaceae, R. L. Wilson, C. A. Abel, R. L. Luhman

Journal of the Iowa Academy of Science: JIAS

Pollination of species of Brassicaceae for seed increase at the USDA-ARS North Central Regional Plant Introduction Station (NCRPIS) has been accomplished for several years by using nucleus hives of honey bees, Apis mellifera L., in field cages. Brassicaceae are cool season crops that need pollination from late April to early June in the north temperate zone. Overwintered hives of honey bees need time to strengthen (i.e., increase their numbers) and thus it is difficult to make enough nuclei to meet our early season pollinations needs. Purchasmg package bees from suppliers in the southern U.S. is an expensive alternative. In this …

Distribution And Persistence Of Phyllachora Species On Poaceae In Iowa, A. C. Gabel, L. H. Tiffany

Journal of the Iowa Academy of Science: JIAS

Phytlachora spp. on Poaceae were collected to determine species present, grass hosts and distribution in Iowa. From 1959-1996 the fungus was collected 240 times from 67 different sites in 35 counties. Seven species of Phytlachora were collected on 25 species from 13 genera of grasses. P. graminis was collected 89 times from 43 sites on four species of Agropyron, two species of Calamagrostis, three species of Elymus, Hystrix patula, Panicum virgatum, and Setaria glauca. Seventy-two specimens of P. luteo-maculata on Andropogon gerardii or Schiziichyrium scoparium were collected from 30 sites. The study included 20 collections of P. cynodontis on Bouteloua …

Characterization Of Central Iowa Forests With Permanent Plots, James W. Raich, Donald R. Farrar, Ruth A. Herzberg, Eenam Sin, Cindy L. Johnson-Groh

Journal of the Iowa Academy of Science: JIAS

We describe a standard methodology for establishing and inventorying the woody vegetation in 0.1-ha permanent forest plots and we utilize the data from 86 plots to characterize the mature forest vegetation of central Iowa. Obvious differences existed between bottomland hardwoods and upland forest stands, but disturbed uplands contained species typical of bottomlands. Little-disturbed upland forest plots included a variety of species associations, but variation among plots was continuous. The trees dominating the mature upland forests of central Iowa grow in a wide variety of habitats, with the result that predictability of stand structure at any location is limited. Stands on …

Nebraska Summary: S296 New Holland Ts 110, Nebraska Tractor Test Lab

Nebraska Tractor Tests

ABOUT THE TEST REPORT AND USE OF THE DATA The test data contained in this report are a tabulation of the results of a series of tests. Due to the restricted format of these pages, only a limited amount of data and not all of the tractor specifications are included. The full OECD report contains usually about 30 pages of data and specifications. The test data were obtained for each tractor under similar conditions and therefore, provide a means of comparison of performance based on a limited set of reported data. EXPLANATION OF THE TEST PROCEDURES Purpose The purpose of …
